hi, getting around to trying to get my tachometer to work, never did since purchase. which wire from behind the instrument cluster is responsible for tach and is it fed from eec or the coil itself or tfi? where do i get a pinout of my eec, i can't seem to find an 87 pinout? i took it out and found these serial numbers: efi-sd22a and e7tf-12a650-be1a, what do they mean? is this an 87 eec? Thank you!
